I first found a dollar bill in my pocket. I walked over to the vending machine and looked through the window to make sure I knew what I wanted. There were many rows of candy, snacks, and drinks to choose from I chose a particular candy bar and looked at the letter and number below it. Remembering that letter and number, I put my dollar in the machine, which took my money. I then touched the letter and number on the keypad. The metal arms that held the candy bar in place pushed forward and the machine dropped my candy bar down into a place where I could reach through a door to pick it up. The machine knew that I put too much money in and I heard the sound of coins falling into a slot on the machine, which I used to hand to remove.  I walked away from the vending machine pleased and let the next person use it.
Did the vending machine purchase drop right away, or get stuck?
